DETAILED DESCRIPTION OF THE INVENTION

The ensuing description provides exemplary embodiments only, and is not intended to limit the scope, applicability or configuration of the disclosure. Rather, the ensuing description of the exemplary embodiments will provide those skilled in the art with an enabling description for implementing one or more exemplary embodiments. It being understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the invention as set forth in the appended claims. For example, any detail in one embodiment may not be included in other versions of that embodiment, or may be added to any other embodiment or modified version of the other embodiment.

Specific details are given in the following description to provide a thorough understanding of the embodiments. However, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details. For example, systems, processes, and other elements in the invention may be shown as components in block diagram form in order not to obscure the embodiments in unnecessary detail. In other instances, well-known processes, structures, and techniques may be shown without unnecessary detail in order to avoid obscuring the embodiments.

Embodiments discussed herein allow for a ramp or ramps to be affixed to a shed, storage container, building, vehicle (i.e., truck beds, trailers, recreational vehicles, etc.), towable storage, or other device/structure (hereinafter, collectively, “structure”). Systems, kits, and methods are provided by various embodiments of the invention that will become apparent to those of skill in the art after reading the present disclosure. Turning now to FIG. 1, a ramp system 100 embodiment is shown. The ramp system may include a first component 110 and a second component 120.

First component 110 may include a horizontal portion 112, a vertical portion 114, and a first hook 116. Horizontal portion 112 may be configured to be supported by a top portion of a lip 130 of a structure 132. Horizontal portion 112 may have a width equivalent to a length of lip 130 which supports horizontal portion 112 (i.e., approximately the width of the doorway or less). In some embodiments, horizontal portion 112 may include anti-slip features 113. In some embodiments horizontal portion 112 may consist of, or constitute, sill nosing. First component 110 may couple with lip 130 in any number of possible ways, including fasteners (i.e., screws, nails, etc.), adhesives (i.e., glue), and/or ribs which bite into lip 130. Such coupling mechanisms may be employed anywhere along the interface of first component 110 with lip 130.

Vertical portion 114 may be coupled with an edge of horizontal portion 112 and may be configured to hang downward from horizontal portion 112 along a side portion of lip 130 of structure 132. Vertical portion 114 may have the same width as horizontal portion. 112 (i.e., approximately the width of the doorway or less). First hook 116 may be coupled with vertical portion 114, and may have the same width as the horizontal portion 112 (i.e., approximately the width of the doorway or less). In some embodiments, first hook 116 may have a width less than that of the horizontal portion 112.

Second component 120 may include a first protrusion 122 and a first channel 124. First protrusion 122 may have a maximum width equal to or less than the width of the horizontal portion 112 (i.e., approximately the width of the doorway or less). First protrusion 122 may be configured to be supported by first hook 116. This allows for the ramp, depending on the length of the ramp, the range of motion permitted by the knuckle/hook, as well as surrounding terrain, to extend away from the structure at variable angle. This can allow for the ramp angle to vary as the building and ramp settle into the supporting surface (i.e. the ground) at a different rate.

First channel 124 may be coupled with first protrusion 122, where first channel 124 may have the same width as first protrusion 122 (i.e., equal to or less than the width of the horizontal portion 112 (i.e., approximately the width of the doorway or less)). First channel 124 may be configured to receive a first planar component 140 which forms a sloped surface of a first ramp. In some embodiments, the top exterior of first channel 124 may include anti-slip features 126. Second component 120 may couple with lip first planar component 140 in any number of possible ways, including fasteners (i.e., screws, nails, etc.), adhesives (i.e., glue), and/or ribs which bite into first planar component 140. Such coupling mechanisms may be employed anywhere along the interface of second component 120 with first planar component 140.

In some embodiments, a second hook 118 maybe coupled with vertical portion 114, wherein second hook 118 may have the same width as horizontal portion 110, and is also configured to support first protrusion 122. FIG. 2 shows second hook 118 supporting first protrusion 122. In some embodiments, second hook 118 may have a width less than that of the horizontal portion 112.

While in FIGS. 1 and 2 hooks 116, 118 are shown as being round, and first protrusion 122 is also round and at least partially congruent with hooks 116, 118, other shapes for hooks 116, 188 and first protrusion 122 are also possible. FIG. 3A and FIG. 3B show other potential configurations. System 300 shows an angled protrusion 310, while system 301 shows a straight protrusion 311 and angled hooks 312, 313. Also note that (a) protrusion 310 is located at the opposite corner of channel 320 than channels 124, 321, and that (b) the first component may not have a horizontal portion, instead coupling directly to the side of the lip, as shown in FIG. 3B. In these or other embodiments, the second component may also not include a channel, but instead couple to one side or edge of the planar component. For example, the second component may couple to the bottom of the planar component, the end/edge of the planar component, and/or the top of planar component. These variations may be possible in any embodiment discussed herein.

FIGS. 4A-4D show variations 401, 402, 403, 404 of first component 110 which include only a first hook 116, and not a second hook 118. In yet other embodiments, a first component may have three or more hooks to allow the ramp to be provided at a number of possible elevations.

FIGS. 5A-5C show variations 501, 502, 503 of second component 120 which have differing channel widths (501 versus 503), and/or different lengths of channel walls (501, 503 versus 502).

FIGS. 6A-6B show protrusions 601, 602 which have a hooked portion 603, 604 which assist in resisting movement of second component 605, 606 from hook 607, 608. This detail may be present in various embodiments of the invention to assist in preventing accidental or unintentional removal of the ramp from the structure. If second component 605, 606 is rotated too far downward, or pulled away from hook 607, 608, hooked portion 603, 604 may engage the tip of hook 607, 608, thereby discouraging disengagement of the ramp. Hooks 607, 608 may also have bulbous ends, as shown, to at least partially assist in preventing removal of the ramp from the structure.

FIG. 7 shows one example 700 of why multiple hooks 701, 702 may be present in some embodiments. When door 705 is closed, having ramp 710 engaged in hook 701 may not be possible because of the overhang of door 705. When door 705 is to be opened or closed, ramp 710 may therefore be engaged in hook 702. While door 705 is open, and access to the structure desired, ramp 710 may be engaged in hook 701 to bring the top of ramp 710 in closer proximity to the level of floor 715. Thus, hook 701 provides for easy access to the structure, while hook 702 provides for storage of the ramp in the meantime, as well as ramped access when height of the ramp compared to the level of floor 715 is not critical (i.e., when a dolly or other loading device is not being employed).

FIG. 8A shows one embodiment 800 where a single ramp 801 is employed. In this embodiment, single ramp 801 provides access to the structure. The width (‘W₁’) of single ramp 801 may be approximately equal to or less than the width of a corresponding door or other egress from the structure. FIG. 8B shows an alternative embodiment 810 where two ramps 811 are employed. In this embodiment, the width (‘W₂’) of each ramp 811 may be less than the width of a corresponding door or other egress from the structure. Additionally, two second components 820 may be necessary in this embodiment (one for each ramp 811), but only one first component 830 may be used. In other embodiments, multiple separate smaller first components 830 may be used, one at each ramp connection. Embodiments similar to 810 may allow a means of providing vehicle ramps, where wheels may roll up-and-down ramps 811.

The invention has now been described in detail for the purposes of clarity and understanding. However, it will be appreciated that certain changes and modifications may be practiced within the scope of the appended claims.
